HEATING APPARATUS.

To all whom it may concern."

Be it known that we, JOHN W. WINTER- BOTTOM and RALPH F. Wmrnnno'r'roim'both citizens of the United States of America, and both residents of, Waterloo, Black Hawk County, Iowa, have invented gertain new and useful Improvements in Heating Apparatus, of which the following is a specification.

Our invention relates to improvements in heating apparatus, and particularly to radiators adapted for both direct and indirect radiation of'heat, whether by direct radiation from exposed surfaces or by indirect heating by conduction to a current of air in circulation through the apparatus.

One object of our improvements is to supply heating and ventilating unit elements of hollow and communicating construction, for steam, vacuum, vapor or hot water heating as desired, the outer surfaces of the as sembled units being effective within a room for direct radiation of heat therei-nto, and inner passages within the convolutions of said units serving to conduct therethrough air under artificial or natural pressure, heating this air by conduction before delivering it warmed into the air of the room.

Another object is to use the a, paratus as a re-heater by passing through it air under pressure which has been previously initially heated by heating means at a. remote location.

Another object of our improvements is to so position air-receiving and air-delivery vents of said apparatus as to receive air from the room adjacent the floor thereof and to deliver warmed air at the top of the apparatus in order to effect proper and natural circulation of air within the room by first withdrawing the colder air nearest the floor.

Another object is to provide the apparatus with a by-pass controlled by a suitable valve, for diverting a portion of the air-supply from the central heating passages when it is found desirable to,.'adjustably vary the temperature of the warmed air delivered into the room.

- These objects have been accomplished by.

the means which are hereinafter described and claimed, but it is to be understood that various modifications may be effected in thedetails of the construction of the apparatus without departing from the principles of the invention, or the proper protection thereof.

In the drawings, Fig. 1 is a-view, partly in front elevation and partly in section, of assembled radiator units of our improved heating apparatus. Fig. 2 is a vertical transverse section of this, apparatus including air-pressure and primary heating means,

with parts broken away, Fig. 3 is a horiof intermediate units 1 placed between and assembled with end units 2, all said unitary elements being hollow inter-communicating structures made of, any suitable'material and of dimensions and proportions to suit any exlgency. I

Each end element 2 has at top and bottom the orificed seats 39 and 7 respectively containing the nipples 40 and 8, as in ordi nary radiator practice, the upper ones constituting a horizontal passage to receive a fluid heating medium such as steam from a source of supply and deliver it into the upper part of the hollow of each of the sections 2 and 1, so that the steam after transversing the different channels therein may be delivered'from the lower passage to a conduit not shown for evacuation exterior of the apparatus and room. a

Each of the intermediate sections or hollow elements 1 of the radiator comprises hollow uprights 1 and 5 connected by spaced sloping transverse conduits connected by webs 6 and each conduitjis made up of diminished end parts 4 and an enlarged middle part 3, the latter preferably but not necessarily of diamond shape cross-section to increase its exterior radiating surface. The upper ends of the risers 1 and 5 are in communication with a relatively large cavity 12. in the upper part of the radiator, and between the elements 1 and 2 a number of ports 9 and 10 are respectively provided in the back and front of the radiator to serve. as air-ports. Several crossrods 36 are fixed across the cavity 12 and upon them is supported removably a water-container 37 being an open top tank. This tank is preferably but not necessarily shaped with an elongated inner inversion 38 of its bottom, thus supplying a larger surface for the conduction of heat into the water content. Porous filtering material 41 is held below the ports 10 by screening netting 42.

Below the radiator and communicating therewith byway of ports 14 and 15 respectively are upper and lower compartments or air-distributing chambers 13 and 19. An air-insulated by-pass 16 or more than one, is positionedback of the radiator and may be received-in a recess in the Wall part 17, the upperp'art' of the by-pass delivering into said cavity 12. through the ports 9. The lower endof the by-pass conimunicates with the upper distributing chamber 13, the communication being controlled adjustably or closed by means of a rock-valve or damper 18.

Opposite each other in the rear and front walls of the lower distributing-chamber 19 are openings 22 and 21 respectively independently closed or adjustably variably opened by valves 26 and 23, but these valves may be operated by means of a single slidero and link connections 20 and 25 or 24 as shown.

A rotary fan bloWer may be installed within the lower compartment 19 if desired, but when the apparatus is to be such as to. have a rotary blower delivering air under pressure to a number-of radiators, as in an apartment house or other building, such blower may be located at a remote distance in another room. As shown in said Fig. 2,

7 this arrangement is illustrated, wherein the rotary blower 2930 is mounted in a housing 28 in another apartment, said housing having communication by way of a conduit 27 with the receiving opening 22 of the chamber 19. The housing 28 may have a communicating extension 31 containing a pre-heating coil 32 for initially heating to a desired temperature air received through the open end of the extension, said end being traversed by a reticulated screen 33. Withsaid extension end may be mounted rocking valves 34, to be actuated manually by a shifting-device 35 to regulate entrance of fresh'air.

The valve 18 may be opened to a desired amount to divert a portion of air from the distributing-chamber 13 from the passages of the ,radiator to the by-pass 16, thence to the cavity 12 to mix with the heated air arising thereinto from the radiator passages, thus tempering the air delivered into the. room through the vent-openings 10. This air also delivers into the room a sufiicient amount of vapor from the centents of the container 37.

The lower valves 23-may be completel opened while the other valves 26 are close to thereby induce-circulation of air in the room, for it will be observed that hot air delivered at the top of the radiator will enter the room and push beforeit the colder air adjacent the floor and into the opening 21. This creates a complete and diffused movement of air through the room, without unpleasant drafts, ventilating and humidifying the room thoroughly. In practice, as shown in said Fig. 2, the valves 26 and 23 are both left partly open, as the forced air supply from the blower 29 accelerates and increases the fresh warmed air circulation in the room, a necessary desider'atum in rooms occupied by a number of persons.

It will be observed that as the hollow radiator elements 1 are uncased, their outer surfaces give a direct radiation of heat to the exterior air in the apartment at all times, during, and regardless of whether the air moving up through the air-passages of the radiator is under forced or natural draft.

As the transverse parts 43 of the radiator elements are substantiallyhorizontal and of relatively large radiating surfaces, ascending air in the passages is baflled thereagainst and by the Webs 6, to effect quick and maximumheating, and the parts 43 are preferably staggered in the alternated elements 1, to provide winding passages, enhancing the heating of the air while in the radiator. As the parts 4-3 are slightly sloped, water of condensation is quickly delivered to the lower conduit for evacuation.

A small dead-end steam-tube 43 is seated in the lower steam conduit of the radiator, with the end perforation 44 to. exhaust its air, and is used to keep the baseof the radiator warm. This is necessar when the main supply of steam is shut o and prevents freezing of water of condensation. Doors 46 give access to the cavity 12 for insertion or removal of the container 37.

Having described our invention, what we claim as new, and desire to secure by Let ters Patent, is:
